Longitudinal Gut Microbiota Composition During Perinatal period in Women with Different Intensities of Depressive Symptoms.

Background: Depressive symptoms during perinatal significantly impact mothers and infants. Emerging evidence suggests a connection between gut microbiota and mood regulation. This study investigated whether depressive symptoms are associated with changes in the gut microbiota of women during the perinatal period.

Plasma proteome profiling reveals molecular mechanisms underlying the effects of daily consumption of 'Bahia' and 'Cara Cara' orange juices.

Orange juice is an important food source of bioactive compounds, mainly the flavanones hesperidin and narirutin. This study aimed to investigate the underlying molecular mechanisms of action of orange juice's health properties by analyzing changes in the plasma proteome of healthy Brazilian volunteers after consuming juices made from 'Bahia' (BOJ-source of flavanones) and 'Cara Cara' (CCOJ-source of flavanones and carotenoids) oranges cultivated in Brazil. We used an untargeted proteomic approach, with a particular emphasis on the juices' effects on blood coagulant activity.

Venomous Noodles: The Evolution of Toxins in Nemertea through Positive Selection and Gene Duplication.

Some, probably most and perhaps all, members of the phylum Nemertea are poisonous, documented so far from marine and benthic specimens. Although the toxicity of these animals has been long known, systematic studies on the characterization of toxins, mechanisms of toxicity, and toxin evolution for this group are scarce. Here, we present the first investigation of the molecular evolution of toxins in Nemertea.

Blood orange juice intake changes specific bacteria of gut microbiota associated with cardiometabolic biomarkers.

Blood orange juice is an important source of flavanones and anthocyanins, mainly hesperidin, narirutin, and cyanidin-3--glucoside. The benefits of these bioactive compounds have been reported, but the mechanistic details behind their biological effects are not well established. This study investigated the effects of Moro orange ( L.

Ethylene and Auxin: Hormonal Regulation of Volatile Compound Production During Tomato ( L.) Fruit Ripening.

As the auxin-ethylene interaction in climacteric fruit ripening has been highlighted, the hormonal regulation of aroma changes in climacteric fruits requires clarification. The influence of both phytohormones on the volatile organic compound (VOC) metabolism was evaluated during tomato ( L.) fruit ripening.

Blood pressure and body fat % reduction is mainly related to flavanone phase II conjugates and minor extension by phenolic acid after long-term intake of orange juice.

Hesperidin and narirutin are the major flavanones present in orange juice, and they are associated with a reduction in risk of cardiometabolic disease. However, there is heterogeneity in their biological responses, which is partly due to the large interindividual variation in these flavonoids' bioavailability. We investigated the relation between interindividual variability in the excretion of phase II conjugates and gut-derived phenolic acids, and cardiometabolic biomarkers response.

Brazilian native passion fruit (Passiflora tenuifila Killip) is a rich source of proanthocyanidins, carotenoids, and dietary fiber.

Passiflora tenuifila is a Brazilian native passion fruit consumed by the local population and is a dietary source of bioactive compounds with potential biological activity. The aim of this study is to evaluate the nutritional value of P. tenuifila fruit and its bioactive compounds at two ripening stages.

Stratification of Volunteers According to Flavanone Metabolite Excretion and Phase II Metabolism Profile after Single Doses of 'Pera' Orange and 'Moro' Blood Orange Juices.

Large interindividual variations in the biological response to citrus flavanones have been observed, and this could be associated with high variations in their bioavailability. The aim of this study was to identify the main determinants underlying interindividual differences in citrus flavanone metabolism and excretion. In a randomized cross-over study, non-obese and obese volunteers, aged 19-40 years, ingested single doses of Pera and Moro orange juices, and urine was collected for 24 h.

Prophylactic Use of Negative Pressure Wound Therapy Reduces Surgical Site Infections in Elective Colorectal Surgery: A Prospective Cohort Study.

The main purpose was to assess the efficacy of negative pressure wound therapy (NPWT) for surgical site infection (SSI) in elective open and laparoscopic open-assisted colorectal surgery. The primary end point was to establish SSI within 30 days post-operatively. The secondary aim was hospital stay and to assess SSI predictors in a multivariable analysis.

Incidence and risk factors for incisional hernia after temporary loop ileostomy closure: choosing candidates for prophylactic mesh placement.

Objectives: The primary aim of this study was to identify the incisional hernia rate after temporary loop ileostomy closure. Secondary outcomes were determining the risk factors linked to this incisional hernia, which could improve the patient selection for mesh prophylaxis.

Methods: Retrospective cohort study of all consecutive patients with temporary loop ileostomy reversal through a peristomal incision from 1st January 2011 to 1st January 2017 at our centre.

Chitosan oligosaccharides affect xanthone and VOC biosynthesis in Hypericum perforatum root cultures and enhance the antifungal activity of root extracts.

Water-soluble chitosan oligosaccharides (COS) affect xanthone and volatile organic compound content, as well as antifungal activity against human pathogenic fungi of extracts obtained from Hypericum perforatum root cultures. Several studies have demonstrated the elicitor power of chitosan on xanthone biosynthesis in root cultures of H. perforatum.

Application of dietary fiber method AOAC 2011.25 in fruit and comparison with AOAC 991.43 method.

AOAC 2011.25 method enables the quantification of most of the dietary fiber (DF) components according to the definition proposed by Codex Alimentarius. This study aimed to compare the DF content in fruits analyzed by the AOAC 2011.

Is endosonography useful to select patients for endoscopic treatment of rectal cancer?

Aim: in recent years there have been remarkable advances in the treatment of rectal cancer, stimulated by a general tendency towards conservative treatment, and aided by the development of diagnostic tools that allow the surgeon to select the most suitable tumors for treatment. In some cases, conservative local excision by transanal endoscopic microsurgery (TEM) may be appropriate. We analyzed the value of transrectal endosonography for the preoperative staging of rectal cancer previous to TEM.

Clinical, histopathological, cytogenetic and prognostic differences between mucinous and nonmucinous colorectal adenocarcinomas.

Objective: To assess the clinical and biological significance of histological typing of colorectal carcinomas.

Patients And Methods: The retrospective analysis of 142 consecutive patients who underwent surgical resection of a mucinous (MC; n = 27; 19%) or a nonmucinous (nMC; n = 115; 81%) colorectal adenocarcinoma was carried out. The two groups were compared in terms of the clinical features, p53 gene expression (antiserum CM1), proliferating cell nuclear antigen (PCNA) labeling index, DNA ploidy (by flow cytometry), histopathological features, prognosis and recurrence rate.

The value of Hughes-Cardiff classification in the management of perianal Crohn's disease.

Purpose: The aim of this study was to assess the value of Hughes' pathogenic classification in the prognosis and management of perianal Crohn's disease (CD).

Patients And Methods: This classification differentiates between purely inflammatory lesions and their mechanical or septic complications, and defines the presence of ulceration (U), fistula (F) and stricture (S), which are assigned a score of 0, 1 or 2 according to the severity and associated conditions, proximal intestinal involvement and disease activity (A, P and D). Of a series of 96 patients with CD, 12 underwent 16 procedures involving anesthesia to treat symptomatic anal lesions.
